'Supernatural': The greatest episodes from the cult drama

Boo! It's Hallowe'en and we're just days away from the DVD release of Supernatural's seventh season - Jensen Ackles and Jared Padalecki return for the fun, spooky drama's latest run, which sees the dashing pair take on the terrifying Leviathans!

Supernatural: The Complete Seventh Season hits UK stores on November 5 and to celebrate the Week in Geek is going to take a look back at some of the show's finest episodes. Carry on, my wayward son...

While many series suffer from a weak and uneven pilot episode, still trying to decipher exactly what the show is meant to be, Supernatural - if you'll excuse the mixed metaphors - hit it out of the park straight out of the gate. Eric Kripke's pilot episode introduced our two likeable leads Sam (Padalecki) and Dean (Ackles) and featured a memorable threat - Sarah Shahi's terrifying Woman in White - and some vivid horror imagery - poor Mary (Samantha Smith) and Jessica (Adrianne Palicki), burnt to a crisp by ol' Yellow Eyes...

'What Is and What Should Never Be' (Episode 2.20) - first aired May 3, 2007

Poor tragic Dean - doomed to live the life of a hunter from an early age. But 'What Is and What Should Never Be' gave him a taste of a normal life as he entered an illusory world where his mother was never killed. Of course, the status quo ultimately had to be restored - when Dean realized that all the people he and Sam had saved in their hunting days had to die so that he could have a happy life, he selflessly gave up his idyllic new existence... *sob*

Oftentimes the best Supernatural episodes are those that focus on Sam and Dean's brotherly bond and 'Mystery Spot' is no exception. The third season of Supernatural followed Sam's attempts to save his sibling from a Hellish fate and his efforts seemed more futile than ever in this episode, which saw Dean killed, over and over again, in a variety of gruesome ways as part of a bizarre Groundhog Day time loop. Rise and shine, Sammy!

With the Apocalypse looming, Dean got a terrifying vision of the future in 'The End', which took place in a dystopian world where humans have been infected with a demonic disease, transforming them into strange, zombie-like creatures. Worse still, in this nightmare vision, Sam has become Lucifer's vessel and Dean himself is a bitter shell of his former self. This standout episode raised the stakes for Supernatural's fifth season and featured a top-notch performance from Jensen Ackles.

One of the best ever Supernatural episodes will be available to watch time and time again from November 5 - season seven installment 'Death's Door' saw faithful Bobby (Jim Beaver) wandering the afterlife after taking a bullet to the head. Forced to relive his own worst experiences and aided by his late friend Rufus (Steven Williams), Bobby ultimately bid a sad farewell to his surrogate sons Sam and Dean before passing over into the spirit world...
